RUBBER SHOE.

SPECIFICATION forming part'of Letters Patent No. 509,927, dated December5, 1893.

Application tiled July 26, 1893. Serial No. 481.509. (No specimens.)

.To all whom it may concern;

Beit known that I, MAX MAYER, a citizen of the United States, and aresident of Denver, in the county of Arapahoe and State of Colorado,haveinvented certain new and useful Improvements in Rubber Boots orShoes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in rubber boots or shoes, and hasfor its object to provide,in connection with the sole and heel portionsof such devices, safety attachments in the form of strips of leatherextending transversely across the same for the purpose of preventingslipping upon ice and snow and thereby materially assisting pedalmovement.

With this and other objects in View, the invention consists of theconstruction and arrangement of the several parts, which will be morefully hereinafter described and claimed.

In the drawings: Figure l is a perspective view of the sole and heelportion of a rubber boot or shoe, showing the improved attach-m mentsapplied in connection therewith. Fig. 2 is a central, longitudinal,vertical section of a sole and heel, as shown in Fig. l.

Similar numerals of reference are employed toindicate correspondingpartsin both figures. Referring to the drawings, the numerals l and 2designate the sole and heel respectively, of a rubber over-shoe or arubber boot,

and extending transversely across the same at proper distances orintervals are grooves 3 which are formed when the rubber is goingthrough the process of molding to construct the boot or shoe, andcentrally located in the said grooves and projecting outward therefromis a series of rivets 4, whose Shanks are barbed backwardly or upwardlywhen the boot or shoe is in proper position. The said rivets are put inposition during the process of molding,l and are thereby held firmly inplace. Seated in the said grooves 3 are leather strips 5, which projectbeyond the surface of the sole and heel and through which are passed theprojecting ends of the rivets. In securing the leather strips 5 in thegrooves the ends of the rivets are upset and swaged down and the saidleather strips are thereby securely retained in the said grooves.

By the formation set forth, a series of ribs are provided which takeinto the snow and give the feet of the wearer a purchase in walking toprevent backward slipping or sliding movement. On ice the surfaces ofthe ribs or leather strips rmly contact with the slippery surface andthe rubber of the sole and heel of the shoe coacting therewith, preventthe feet from sliding either forwardly 01' back wardly, as the ribs arearranged transversely and form abutting or resisting shoulders.

In applying the leather strips to the sole and heel, of a boot or shoe,they are not put in position until after the said sole and heel areformed, as the heat would otherwise destroy the leather and render thesame useless. It will be understood that any form of rivet may beemployed, so long as the points of the same are soft and will easilyclinch or be fastened in the manner previously stated. The device entireis simple in its construction and is especially useful in walking oversteep roads to prevent slipping backwardly. The leather strips alsoincrease the durability of the rubber sole orheel by removing a portionof the wear therefrom.

It will be obviously apparent that many minor changes in theconstruction and arrangement of the several parts might be made forthose shown and described, so long as they are within the scope of theinvention, without in the least departing from the nature or spirit ofthe latter.

Having thus described the invention, what is claimed as new is- In arubber boot or over-shoe, the combination of the sole and heel portionsthereof, having grooves formed therein, and rivets projecting from saidgrooves and seated in position during the casting or molding of thesole, and leather strips, fitted in said grooves and secured by the saidrivets, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

MAX MAYER.
